System and method for electronic text analysis and contextual feedback

ABSTRACT

Analyzing communications to determine appropriateness and provide recommendations based on prior communications. Prior communications may create a baseline tone based on the sentiment, words, or phrases used in previous communications between the user and the intended recipient and/or other user recipient pairs. Machine learning techniques may be used to continuously update a baseline tone.

BACKGROUND 1. Technical Field

The present disclosure relates to a system and method for automaticallyanalyzing text in an electronic document, and providing contextualfeedback on content sentiment.

2. Introduction

Emails are a prevalent means for individuals to communicate bothprofessionally and personally. The tone that is appropriate for an emailmay differ depending on the subject of the email and sender andrecipient of the email. In the professional context, an email that isappropriate for a peer may not be appropriate for a superior, even ifthe information contained in the email is the same. Similarly, an emailmay not be appropriate if the subject of the email is serious even ifthe email would be appropriate if the email was regarding a lessimportant subject. Given the large number of electronic documents thatare created and stored, the tone and content of electronic documentscannot be tracked or analyzed. Therefore, it may be advantageous toautomatically generate text or suggestions based on several factorsincluding the sender's email history and habits, the recipient of theemail, or the subject of the email. It may be further advantageous toautomatically provide text suggestions or the tone of the email beforethe email is sent. Machine learning may provide an advantageous way toevaluate the appropriateness of email tone based on a sender's or groupof senders' email tone history and the responses received by recipientsof emails with given tones.

DETAILED DESCRIPTION

Various embodiments of the disclosure are described in detail below.While specific implementations are described, it should be understoodthat this is done for illustration purposes only. Other components andconfigurations may be used without parting from the spirit and scope ofthe disclosure.

The present disclosure is directed to methods, systems, andnon-transitory computer-readable media for natural language processingand analysis of electronic documents. The analysis may determine thetone and sentiment of the electronic document, such as an email.

It is therefore advantageous to automatically evaluate the text of anemail and provide suggested text or feedback on the appropriateness ofthe email tone, sentiment, and content before the email is sent. Inother embodiments, the analysis may determine the email tone, sentiment,and content of the document. The analysis of the electronic document maybe performed by a tone interpreter or a content analyzer. A recipientdatabase may store the baseline tone of electronic documents from asender and associate the baseline tone with a recipient of theelectronic documents. The email sentiment, tone, and content may beevaluated using natural language processing. The natural languageprocessing may be rule based or machine learning based. The email may beprocessed, and several categories may be assigned to the email. In otherembodiments, the categories may be assigned to words or passages withinthe email. A word database may contain words, phrases, and punctuationthat are associated with different tone or sentiment categories. Thecategories may be tone or sentiment categories such as passive,aggressive, informal, angry, sentimental, dismissive, serious, personal,professional, confidential, etc. In some embodiments, the tone may beassociated with a recipient or a sender-recipient pair. The tone scorefor the recipient or sender-recipient pair may be stored in therecipient database. In other embodiments, the sender and recipient maybe assigned categories and the tone may be associated with thesender-recipient category pair.

Several emails may be analyzed to create a baseline tone betweenrecipients or recipient types. The recipient type may be determined by ajob-title analyzer, or a party analyzer based on information input intothe electronic document or the user account. The baseline tone maychange over time using machine learning techniques. For example, themachine learning techniques may include Linear Regression, LogisticRegression, Decision Tree, SVM (Support Vector Machine), Naive Bayes,kNN (k—Nearest Neighbors), K-Means, Random Forest, DimensionalityReduction Algorithms, Gradient Boosting Algorithms, XGBoost, LightGBM,and/or Catboost algorithms. In some embodiments, the baseline tone mayalso be associated with the content or subject of the emails. Thecontent or subject may be determined using natural language processing,key words, or may be identified by a user. In other embodiments, abaseline tone may be pre-determined for certain sender-recipient pairsor the email content and categories. In still further embodiments, thetone of the response email may also be evaluated in a tone interpreter,and the response tone may be used in determining the effectiveness ofthe tone of the initial email to better inform the machine learningalgorithm. The baseline tone may be stored in a database and associatedwith the author(s), recipient(s), or author(s)/recipient(s)

A sender may author new emails. The new email's tone, content, andsentiment may be analyzed in a tone interpreter, content analyzer, orcontent identifier and may be compared to the baseline tone. The toneanalyzer may review the email to determine whether the email has a tonethat may be inappropriate, the tone identifier may compare the contentsof the email to words or phrases that may be identified as correspondingto a tone category. The content analyzer may determine if the overallcontent of the email. For example, natural language or other processingmethods may be used to determine whether the content of the emailpertains to a bill, a contract negotiation, and personnel discussion,etc. The content identifier may identify the presence of any specificcontent of the email, for example, if a specific client is mention, thecontent identifier may identify the client as content of the email. Someembodiments may combine a tone interpreter, and content analyzer, and acontent identifier into a single processing object that performs each ofthe task of the tone identifier, content analyzer, and contentidentifier. If the new email is found to differ from the baseline tone,a notification may be provided to the sender by a warning generator. Thenotification may highlight the passages that differ from the baselinesentiment or tone. Determining a sentiment or tone may be done byassigning the email or passage a sentiment or tone score. In embodimentswhere the email is categorized in its entirety, the warning generatormay generate a pop-up message or meter that indicates tone. Inembodiments where a meter is used to display the sentiment, tone, orscore, the meter may be for an individual tone category. In someembodiments multiple meters may be displayed. For example, anaggressiveness meter and a formality meter may separately be displayed.In still further embodiments, one or more meters may be a combination ofdifferent categories. In other embodiments, the tone may be evaluatedand the category that the email, word, or passage falls into may beidentified to the user by highlighting, underlying, or a pop-up message.In still further embodiments, alternative language or phrasing may beprovided that is consistent with the baseline tone.

In some embodiments a tone identifier and content identifier may be usedalone or in combination with the tone interpreter or content analyzer.In embodiments utilizing a tone identifier or content identifier,certain words or phrases may the pre-determined as corresponding to acertain tone or content category. In these embodiments, the tone orcontent identifier may flag or designate an email, word, or passage asbelonging to a tone of content category when the word or passage ispresent.

Emails are a predominant form of communication in professionalenvironments. Often the tone or sentiment of the email can be asimportant as the content of the email. For example, an aggressive orunprofessional tone may obscure or detract from an email where thecontent would otherwise be acceptable to the recipient. Additionally,the sentiment, tone, and formality of an email may differ depending onthe relationship between the sender and recipient(s). For example, asender communicating with a peer may use a more casual tone than thesender would when dealing with a superior or a client. It may bedifficult for a sender to maintain the appropriate tone when sendingmultiple emails to multiple recipients in a short period of time.Additionally, a sender may have personal thoughts or opinions about thesubject of an email or the recipient, however, it may not be appropriatefor the sender's personal thoughts or opinions to be reflected in theemail. The thoughts, feelings, or emotions of the sender may consciouslyor subconsciously be reflected by the tone or sentiment of the email.

Email tone or sentiment can be detected by a recipient in ways that maynot be immediately apparent to the sender. For example, the word choice,punctuation, capitalization or sentence structure used in an email maycreate a tone or sentiment perception that is not intended by thesender. Sending an email with an inappropriate tone or sentiment may bedetrimental to the sender, recipient, or the business. For example, anunintended tone may cause a recipient to misinterpret the content of theemail and take actions based on an interpretation that the sender doesnot intend. A sender may be harmed if an email is perceived asunprofessional or aggressive which may negatively affect the sender'sreputation or may result in a loss of business. Businesses may also beadversely affected when its employees are not effectively communicatingdue to misinterpretation of tone. Further, inappropriate tone orsentiment in an email may result in liability or public embarrassmentfor a business as emails are frequently leaked and discovered duringlitigation. For example, a casual tone when discussing a safety concernmay create liability whereas a more serious tone may indicate that thematter was thoughtfully addressed.

Additionally, some email content may be appropriate for some recipientsbut not others. Confidential client information, for example, must becarefully siloed from other clients or even other members of thebusiness. However, this information may be inappropriately shared byunintentionally naming the wrong recipient. Further, an employee may notbe aware that some information is not to be shared with a party and mayintentionally share inappropriate information to the detriment of thebusiness's credibility and the client's interest.

With reference to FIG. 1 , an exemplary system includes ageneral-purpose computing device 100, including a processing unit (CPUor processor) 120 and a system bus 110 that couples various systemcomponents including the system memory 130 such as read-only memory(ROM) 140 and random access memory (RAM) 150 to the processor 120. Thecomputing device 100 can include a cache of high-speed memory connecteddirectly with, in close proximity to, or integrated as part of theprocessor 120. The computing device 100 copies data from the memory 130and/or the storage device 160 to the cache for quick access by theprocessor 120. In this way, the cache provides a performance boost thatavoids processor 120 delays while waiting for data. These and othermodules can control or be configured to control the processor 120 toperform various actions. Other system memory 130 may be available foruse as well. The memory 130 can include multiple different types ofmemory with different performance characteristics. It can be appreciatedthat the disclosure may operate on a computing device 100 with more thanone processor 120 or on a group or cluster of computing devicesnetworked together to provide greater processing capability. Theprocessor 120 can include any general-purpose processor and a hardwaremodule or software module, such as module 1 162, module 2 164, andmodule 3 166 stored in storage device 160, configured to control theprocessor 120 as well as a special-purpose processor where softwareinstructions are incorporated into the actual processor design. Theprocessor 120 may essentially be a completely self-contained computingsystem, containing multiple cores or processors, a bus, memorycontroller, cache, etc. A multi-core processor may be symmetric orasymmetric.

The system bus 110 may be any of several types of bus structuresincluding a memory bus or memory controller, a peripheral bus, and alocal bus using any of a variety of bus architectures. A basicinput/output (BIOS) stored in ROM 140 or the like, may provide the basicroutine that helps to transfer information between elements within thecomputing device 100, such as during start-up. The computing device 100further includes storage devices 160 such as a hard disk drive, amagnetic disk drive, an optical disk drive, tape drive or the like. Thestorage device 160 can include software modules 162, 164, 166 forcontrolling the processor 120. Other hardware or software modules arecontemplated. The storage device 160 is connected to the system bus 110by a drive interface. The drives and the associated computer-readablestorage media provide nonvolatile storage of computer-readableinstructions, data structures, program modules and other data for thecomputing device 100. In one aspect, a hardware module that performs aparticular function includes the software component stored in a tangiblecomputer-readable storage medium in connection with the necessaryhardware components, such as the processor 120, system bus 110, anoutput device 170 that might be a display, and so forth, to carry outthe function. In another aspect, the system can use a processor andcomputer-readable storage medium to store instructions which, whenexecuted by the processor, cause the processor to perform a method orother specific actions. The basic components and appropriate variationsare contemplated depending on the type of device, such as whether thecomputing device 100 is a small, handheld computing device, a desktopcomputer, or a computer server.

Although the exemplary embodiment described herein employs the storagedevices 160 that may be a hard disk, other types of computer-readablemedia which can store data that are accessible by a computer, such asmagnetic cassettes, flash memory cards, digital versatile disks,cartridges, random access memories (RAMs) 150, and read-only memory(ROM) 140, may also be used in the exemplary operating environment.Tangible computer-readable storage media, computer-readable storagedevices, or computer-readable memory devices, expressly exclude mediasuch as transitory waves, energy, carrier signals, electromagneticwaves, and signals per se.

To enable user interaction with the computing device 100, an inputdevice 190 represents any number of input mechanisms, such as amicrophone for speech, a touch-sensitive screen for gesture or graphicalinput, keyboard, mouse, motion input, speech and so forth. An outputdevice 170 can also be one or more of a number of output mechanismsknown to those of skill in the art. In some instances, multimodalsystems enable a user to provide multiple types of input to communicatewith the computing device 100. The communications interface 180generally governs and manages the user input and system output. There isno restriction on operating on any particular hardware arrangement andtherefore the basic features here may easily be substituted for improvedhardware or firmware arrangements as they are developed.

Use of language such as “at least one of X, Y, and Z,” “at least one ofX, Y, or Z,” “at least one or more of X, Y, and Z,” “at least one ormore of X, Y, or Z,” “at least one or more of X, Y, and/or Z,” or “atleast one of X, Y, and/or Z,” are intended to be inclusive of both asingle item (e.g., just X, or just Y, or just Z) and multiple items(e.g., {X and Y}, {X and Z}, {Y and Z}, or {X, Y, and Z}). The phrase“at least one of” and similar phrases are not intended to convey arequirement that each possible item must be present, although eachpossible item may be present.

FIG. 2 depicts example method 200. At 202 the creation of a new emailmay be detected. A new email may be detected when an email window isopened or when a reply option is selected on a user device. At 204 thesender and recipient of the email may be determined. The sender may bedetermined based on the account that is used to send the email. Therecipient may be determined based on the name entered into a recipientcategory in a party analyzer. The party analyzer may receive a party tothe electronic communication created by the electronic communicationapplication. The party analyzer may also receive a party sentiment scorefor the party from a database. The party sentiment score may be a scorebased on previous emails exchanged by the parties. The party analyzermay then compare the party sentiment score to the communicationsentiment score. The party analyzer may determine a party deviationbetween the party sentiment score and the communication sentiment score.

The job-title of the recipient may be determined in a job-titleanalyzer. For example, the job-title analyzer may receive the party tothe electronic communication created by the electronic communicationapplication The job-title identifier may identify a job-title of theparty to the electronic communication, receive a job-title sentimentscore for the job-title from the database, then compare the job-titlesentiment score to the communication sentiment score and determine ajob-title deviation between the job-title sentiment score and thecommunication sentiment score. The recipient may be auto-populated insome examples, such as when the email is a reply. At 206 a baseline tonefor the sender recipient pair may be retrieved. The baseline tone may bebased on previous emails. The baseline tone may be specific to thesender-recipient pair or may be determined based on category, job-title,or position of the sender-recipient pair. For example, if the individualsender is a sales person and the individual recipient is a client, abaseline tone for sales person/client may be assigned. In otherembodiments the baseline tone may be based on the individual salesperson and the individual client. The baseline tone may be stored in adatabase that may be on the sender's computing device or on a devicethat may be accessed by the sender's computing device as well as otherdevices within an organization.

At 208 the email may be parsed by a tone interpreter or tone identifierfor words that indicate a tone. In embodiments using a tone interpreter,parsing words may include using machine learning, natural languageprocessing, and parsing full phrases, full sentences, and fullparagraphs. The tone interpreter may then determine the overall tone ofthe email. In embodiments utilizing a tone identifier, the email may beparsed to determine whether specific words or phrases that areassociated with a problematic tone are present in the email. Inembodiments using a tone identifier, certain words or phrases may bepre-determined as having a problematic tone. Words associated with atone may be stored in a word database in embodiments using a toneidentifier. The word database may be provided, and the text in thedocument may be compared to the word database by the content identifieror tone identifier. If the email contains words or phrases that are of aproblematic category, the word or phrase may be flagged. In otherembodiments, the tone identifier may individually assess all words inthe email to determine an overall tone. In embodiments, the subjectmatter may be included in a determination of appropriateness or tone. At210 the words of the email may be compared to words in a database todetermine the tone of the parsed words. In other embodiments the wordsmay be evaluated using an algorithm. In further embodiments, the emailmay be analyzed in a content analyzer. A baseline tone may be adjustedbased on the subject matter of an email or a baseline tone may beassigned based on the subject matter of the email. The subject mattermay be based on the content of the email or may be based on anidentified subject matter determined based on the content or in thesubject line of an email or electronic document, At 212 the number ofwords in a tone or sentiment category may be determined. In furtherembodiments, whether any words fall into a given tone category may bedetermined. The database may store the words and associated categories.Words may be associated with more than one category in the database.Some example categories may include aggressive, passive, neutral, etc.

At 214 the number of words in the given tone categories may be used todetermine a current tone. In embodiments using a tone interpreter, thesentiment score may be based on the number of words in a categorycompared to the total number of words in the email. In other embodimentsthe tone may be normalized by comparing the score to the total number ofwords in the email to the number of words in the neutral category. Infurther examples, if the email contains three (3) words that are in anaggressive tone category and three (3) words that are in a passive tonecategory, the tone may be determined to be neutral. In embodiments usingtone identifier, if there are any words in the aggressive category, thetone may be determined to be aggressive regardless of the presence ofother words in other tone categories.

At 216 the email tone may be compared to the baseline tone retrieved at206. This may be done in a comparison interpreter or by using a tonecorrelation machine learning algorithm. If the email is consistent withthe baseline tone at 218, a notification may be generated at 224 thatindicates that the email is appropriate. If the email is not consistentwith the baseline tone, a warning generator may generate a warning at220 that may indicate that the email is not appropriate. The warninggenerator may provide a warning to the electronic communicationapplication when a deviation is greater than a threshold.

In some embodiments the warning may indicate how the email differs fromthe baseline tone or sentiment. For example, a warning may indicate thatthe email is more aggressive, informal, etc., than other emails betweenthe sender recipient-pair or pre-determined appropriate tone. In stillfurther embodiments, the particular words or phrases that areproblematic may be identified. For example, problematic words or phrasesmay be highlighted within the email. In further embodiments, replacementwords or phrases that are consistent with the baseline tone may besuggested to the sender. Thus, the sender may be notified of the emailtone before the email is sent so that any adjustments to the email maybe made before sending.

FIG. 3 depicts an example method 300. At 302 the emails from asender-recipient pair may be retrieved. At 304 the words or phrases inthe email may be parsed into tone categories. At 306 the number of wordsthat belong to each tone category may be determined. A tone of the emailmay be determined at 308, this may be based on the number of words inthe tone categories in the sender/recipient email pairs. A tone may bebased on a single tone category or a tone may be an aggregate based onmultiple tone categories. At 310 tone score may be assigned to thesender-recipient pair based on the baseline tone. The tone score and itsassigned sender-recipient pair may be provided to the database and thesender-recipient pair baseline tone stored in the database may beupdated at 312 based on the tone score. The tone score may be used toupdate a baseline tone associated with the individual sender-recipientpair or the category of the sender-recipient pair, for example:manager-associate, associate-client, internal-external, manager-manager,etc. The baseline tone may be different for different categories ofsender-recipient pairs based on tone of the communications between thepairs in the past. For example, a manager may have a higher level offormality in client emails than in associate emails. In otherembodiments, the baseline tone may be set by an individual or anorganization so that pairs are given unique tone designations. Forexample, an organization may set a lower baseline tone foraggressiveness between manager/associate pairs than associate/associatepairs. The baseline tone or tones may be saved to a database to beaccessed later and referenced when new emails are generated.

At 314 a new email may be generated by a sender and the email generationmay be detected. The sender-recipient pair may be determined at 316. Thesender-recipient pair may be detected based on the email address of thesender and recipient, entered by the user, or determined based on theaccount that the sender or recipient is logged into. The email contentmay be returned to the step at 304 so that the baseline tone iscontinuously updated as additional emails are created and sent.

FIG. 4 depicts example method 400. At 402 the content of an email may beretrieved. Email content retrieval may be done automatically, initiatedby a user selecting a send option or by selecting a tone analysisoption. A tone analysis option may be a selectable option that a sendercan chose before sending an email. A tone analysis may be providedwithin an email generation program or application. At 404 thesender-recipient pair may be determined based on the specificsender/recipient or a sender/recipient category that may be based on therelationship between the sender/recipient with each other within anorganization. At 406 the content of the email may be parsed to determinethe tone of the email. The email tone may be determined using a naturallanguage processor that may be used in combination with a toneidentification program or algorithm. At 408 a baseline tone may beretrieved from a database for a sender-recipient pair. The baseline tonemay be determined based on prior emails sent between thesender-recipient pair. At 410 the baseline tone may be compared to thetone of the email determined in 406. If the tone of the email isconsistent with the baseline tone at 412, an instruction may be sent toa user device to generate a prompt that allows the user device to sendthe email to the recipient. If the baseline tone is inconsistent withthe email tone at 412, the user device may prevent the user from sendingthe email. In other embodiments, a send prompt may not be provided tothe user device and a notification indicating a degree of inconsistencybetween the email and the baseline tone may be determined at 416.

The level of inconsistency between the email tone and the baseline tonemay be evaluated based on a single or multiple tone characteristics. Inother embodiments, an aggregate tone based on multiple categories may bedetermined. For example, if the email tone is determined to be outsideof an aggressive tone range, a send prompt may not be provided. In otherembodiments, if an email's tone is outside of an aggressive tone rangebut is within a positivity tone range, the send prompt may be providedat 414.

The level of inconsistency between the email tone and the baseline tonemay be provided to the user. The level of inconsistency may be providedfor multiple tone categories. In further embodiments, an aggregate toneinconsistency may be provided. At 420 a database or natural languageprogram may provide alternative language that is more consistent withthe baseline tone. For example, if the email or a word or phrase withinan email is too informal, a more formal version of the word or phrasemay be queried. For example, “don't” may be queried and the replacementphrase “do not” may be associated with “don't” in the database. At 422the replacement word or phrase may be provided to the user device.Alternative language may be provided as a pull-down menu for words orphrases that have been identified as problematic. In other embodiments auser may choose to have replacement words or phrases suggested orinserted into the email.

FIG. 5 depicts example method 500. At 502 email generation may bedetected. At 504 the recipient(s) of the email may be detected. At 506the content of the email may be compared to other emails to a recipientthat may be stored in a database or that may be processed into a programthat uses natural language programming to evaluate the generated emailfor comparison to previous email. At 508 the generated email may becompared to previous emails to determine whether the tone of thegenerated email is consistent with emails sent to the recipient in thepast. This may be done using a tone evaluation technique. In furtherembodiments this may be done by a content analyzer based on the contentof the email. For example, if a generated email mentions a topic thathas not been mentioned in previous email, the email may be found to beinconsistent with previous emails at 508. If the content is inconsistentwith previous emails, an inconsistency flag may be generated. This maybe advantageous if the email includes content that is not intended to beshared with the recipient. For example, if a sender has never sent anemail to the recipient that reference a certain subject, entity, orinformation type, a warning may be generated to the sender thatindicates that the indicated recipient may not be the intended recipientof the email. At 512 it may be determined whether an alternative oradditional recipient may be consistent with the subject of the generatedemail. If another recipient is appropriate, an alternative or additionalrecipient may be generated and a flag indicating the alternative oradditional recipient may be generated at 514.

An alternative or additional recipient may be recommended based on thesubject, entity, or information type being consistent with anotherpotential recipient. This may be advantageous to prevent unintendedrecipients from receiving information that might compromiseconfidentiality and may work to prevent members of an organization fromunintentional disclosure of sensitive information. In other embodiments,the tone of the email may differ from emails previously sent to therecipient. A similar notification may be generated to prevent unintendedsender tone from being received by an unintended party.

For example, if the generated email includes a reference to a specificaccount or client that has not previously been referenced in emails tothe recipient, alternative recipient who may have had communicationsconsistent with the generated email may be suggested at 514. This may beadvantageous to avoid information that is intended for one recipientfrom being shared with an unintended recipient. If the user selects asend option, a flag or warning may be provided to the user to allow forthe user to review the content and/or recipient of the email. Theappropriate recipient or content of an email may be determined based onprevious emails sent, for example, using machine learning. In otherembodiments the appropriate recipient or content of an email may bepre-determined. For example, inappropriate content may be also bepre-programmed by a managing operator in order to prevent errant emailsthat disclose confidential information.

FIG. 6 depicts example method 600. At 602 a word may be detected in anemail generated by a user device. The word may be determined to beproblematic based on words that are entered into an email monitoringprogram. In other embodiments a word or phrase may be determined to beproblematic based on the content of emails that have been previouslysent by the sender or the recipient. For example, a word or phrase maybe problematic when the word or phrase differs from the words or phrasesin previous emails specifically or by category. At 604 the detected wordmay be compared to words in a database. The database may contain wordsor phrases that are problematic. For example, words or phrases that mayimplicate confidential information or words that may indicate aninappropriate tone. If a word or phrase within the email does notcorrespond to a problematic word or phrase at 606, the method may end at608. If there are no problematic words or phrases, no tone warning maybe provided to the sender. If, at 606, the email is determined tocontain a word or phrase in a problematic word or phrase category, theword or phrase category may be flagged at 610. The problematic categorymay relate to words or phrases that indicate confidential information,are of a problematic tone, inconsistent with the words or phrases inprevious emails, or inconsistent with a pre-determined baseline tone. Ifa word or phrase does correspond to a category that may be deemedinappropriate for the correspondence, a flag may be set to indicatepotentially inappropriate content at 610.

At 612 the number of words and phrases in the identified categories maybe determined for the entire email. At 614 it may be determined whetherthe number of words or phrases in a category exceeds the number of wordsor phrases in the categories of previous emails from the sender. In someembodiments the percentage of words in an email that are in the categorymay be determined and compared to the normal percentage of words in thecategory. If the words or phrases in a category exceeds the norm at 614,a warning flag may be generated at 616. The warning flag may be providedto a user device or may prompt the device to perform an action, such asproviding additional options to replace words or prevent the email fromsending. In other embodiments an alert that the email may containinappropriate content may be generated. At 618 a sent email may bedetected. The email may be sent regardless of whether a flag is set at616. If the email is not sent, the method may end at 620. If the emailis sent, the email may be analyzed at 622. The content of the email maythen be used to update the number of words and phrases in a category forprevious emails. This may be performed in a learning generator that mayutilize machine learning techniques such as Linear Regression, LogisticRegression, Decision Tree, SVM (Support Vector Machine), Naive Bayes,kNN (k—Nearest Neighbors), K-Means, Random Forest, DimensionalityReduction Algorithms, Gradient Boosting Algorithms, XGBoost, LightGBM,and/or Catboost algorithms.

The database or baseline tone may be continually updated as additionalemails are sent.

FIG. 7 depicts example method 700. At 702 a text passage may beidentified within an email. At 704 the first party to the email, whichmay be the sender, is identified. At 706 the subject of the email may beidentified. The subject may be identified by a content analyzer usingnatural langue processing, a key word search, a user selection, or basedon the subject line of the email At 708 the number of words that belongto a sentiment category may be determined. At 710 a sentiment score maybe assigned to the passage based on the number of words in the sentimentcategory. At 712, the sentiment algorithm may be updated to reflect thesentiment score. The sentiment algorithm may be updated to reflect theparty and subject for the sentiment score. For example, an email from amanager to an employee may read:

“Dave,

I received your analysis and it is completely absurd. Don't ever sendjunk like that again. Your work for the X account was much better.

—CS”

The words “Dave,” “junk,” “don't,” and “CS” may be identified asbelonging to an informal category. The words and phrases “completely”and “don't ever” may be identified as belonging in an aggressivecategory. The words “absurd” and “junk” may be identified as belongingin a negative category. In some embodiments a word may belong to one ormore category. In other embodiments, words may be limited to a singlecategorization. The words “received,” “analysis” “send,” “like,”“again,” “work,” and “X account” may be in a neutral category. The words“much better” may be in a positive category. Common words such as “I,”“your,” “and,” “it,” “is,” or “that” may not be parsed in someembodiments. The frequent or common words may be cleaned from the emailbefore processing.

In the above example:

-   -   the informal category may include four words/phrases: “Dave,”        “junk,” “don't,” and “CS;”    -   the formal category may include zero words or phrases;    -   the aggressive category may include two words or phrases:        “absurd” and “junk;”    -   the negative category may include two words or phrases:        “completely” and “don't ever;” and    -   the positive category may contain one word or phrase: “much        better.”        A sentiment score may be determined based on the number of words        in the positive and negative sentiment category. In this example        the positive/negative score may be one because there are two        words or phrases in the negative category and one word or phrase        in the positive category. A formal/informal score may be        negative four because there are four words in the informal        category and no words in the formal category.

At 714 a party algorithm may be updated to reflect the sentiment scorefor the party. At 716 a party classification algorithm may be updated toreflect the sentiment score for the party classification. Whereas theparty may reflect an individual, the party classification may reflect acharacteristic about the individual, for example the individual'sjob-title. At 718 a subject matter algorithm may be updated to reflectthe sentiment score for the subject matter. Thus, the algorithms fordetermining whether sentiment is appropriate may be continually updatedas new emails are generated.

FIG. 8 depicts example method 800. At 802 a new electronic document oremail may be displayed. At 804, a party to the electronic documentcommunication may be identified. The party may be the intendedrecipient. At 806 the party classification may be identified. Theclassification may be some party characteristic, such as therelationship to the sender (i.e. client, manager, peer) or therecipient's organization. At 808 the subject matter of the electronicdocument may be determined. At 810, the text from the electronicdocument may be retrieved. At 812 the text may be analyzed. In someembodiments the text may be parsed to determine the number of words orphrases in the text that correspond to a sentiment category. Theanalysis may be performed with multiple sentiment categories in someembodiments. In other embodiments, an algorithm may be used to determinethe sentiment of the text. At 814 the sentiment score may be assigned tothe electronic document.

At 816 a correlation between the sentiment score for the document may becompared to a predetermined sentiment score. The predetermined sentimentscore may be based on the sentiment score of previous communications. Inother embodiments the sentiment score may be determined by the user ororganization. If the correlation between the predetermined sentimentscore and the electronic document's sentiment score is below athreshold, a notification that the sentiment is not appropriate may begenerated at 820. A low correlation may indicate that the tone orsentiment is an outlier when compared to previous communications. At822, the sentiment score may be compared to a sentiment score for asender or recipient type. For example, a second sentiment score may bepredetermined for emails that are from managers. In this example, amanager sentiment score may be different from a general sentiment score.A sentiment score may be predetermined for all communications within anorganization, but a second sentiment score may be set for managers. Forexample, managers may have a higher formality sentiment score thanothers within the organization.

At 824 the correlation between the sentiment score of the electronicdocument and the party classification score may be generated. If thecorrelation is below a threshold, a notification may be generatedindicating that the sentiment is outside of the norm for communicationsfrom senders in the sender's party classification. At 826 thecorrelation between the sentiment score of the electronic document andthe subject matter score may be generated. If the correlation is below athreshold, a notification may be generated at 828 indicating that thesentiment is outside of the norm for emails related to the subject.
